Laia Andreu Hayles' research focuses on the study of the interactions between forests and the environment and on reconstructing past climate conditions using tree rings and isotopic geochemistry. Warming temperatures associated with global climate change are having dramatic and profound impacts on forests, and her research centers on assessing these changes across several key regions of the planet. She is currently conducting research in boreal, tropical, Central Asian and Mediterranean regions, which are ‘hot spots’ of current climate and environmental change.
